To aZZ whom itjnay concern:

Be it known that l, CHARLES T. HOLLOWAY, States, residing at Bal timore, in the State of Maryland, have inand. useful Improvements in Hand-Grenades for` Fire-Extinguishers, of which the followingv is a specification.

The object of this invention is `to provide a hand-grenade made of frangible material adapted to contain the requisite alkaline solution and liquid acid in separate receptacles, whereby they are kept from chemical combi-A nation until the grenade is-broken. The construction' of the improved hand grenadev whereby the desired result companying drawings, which illustrate what l is deemed the best means of carrying the in- Figure 1 is asectionalview of my improved .hand-grenade. Fig. 2 shows' the washerwhich bv which the may be interposed between therim of the orilice on the shell and the iiange of the acidreceptacle. Fig. 3 shows a disk which may be used to close the mouth of the acid-receptacle. Fig. 4 shows a screw-cap which, when the grenade is constructed as shown in Fig. 1, is employed to retain the disk over the mouth of the acid-reccptacle and to confine the said acid-receptacle 'and alkaline solution within the grenade-shell, Fig. 5 shows the acid-receptacle detached. Fig. 6 illustrates my handgrenade made in a different shape, and shows a modification in the manner ot' securing the acid-receptacle within the grenade-shell. Fig. 71s a detached view of the elastic packing employed for securing the Vacid receptacle within the shell when the grenade is made according to the modification shown in Fig. 6.

- Referring to the drawings, theletter Adesi nates the outer shell of the hand grenade. l This should be made of glass or other suitable frangible material. 1t may have -a nearly .globular form/as shownin Fig. 1, or may have an ordinary bottle shape, as shown 'in Fig. 6. The shape, however, is-immaterial. This outer shell has aneck, b, which serves asa handle u grenade may be grasped.` The neck is provided with an orifice, through which the shell is filled with the solution. In ythe present instance the shell is designed tolbe ceptacle,

Y, is accomplished such will be described,in connectionwith the acl ployed in chemical when 'break the shell and receptacle the said com# lled with an alkaline solution, be used for confining the liquid acid. A re- O, for acid is4 also made of glass or otherfrangible material, and has such shape as will permit it te pass through the orifice in the neck b, and thereby occupy position within though -it may the outer shell. \ln the present instance thel acid-receptacle consists of a straight slim vial closed at the lower end, d, and provided at the upper open end with a flange, e, projecting at a right angle. vBy this construction.

of the two frangible receptacles, when the one is confined within the other, as hereinafter described, the grenade stands ready charged withl thrown into a fire with such force as to components separated as are usually emreextinguishers to pro` f ponents at once enter into chemical combina- I with gas, and thereis no pressure within it to strain the'. shell or prematurely burst it. The components, being kept separate, may each be of the maximum strength, (a thing impossible in hand-grenades hitherto where: the components have been in contact,) whereby the lim ited quantity of the two solutions which a hand grenade can contain will produce a greater volume of carbonio-acid gas, and therefore this -combinationwill be more effective as a fire-extinguisher.

I will now proceed for confining the' solution, acid-receptacle withinthe shell.

The solution'constituting one component is first put into the shell A, and the other liquid component is'put into the receptacle C. The

It will be seen that the acid- 5 receptacle has such position within'the outer receptacle aslto be surrounded by the solution therein, and that the connection between the shell A and receptacle C is only in the neck of the former, Another means of con- Io' iining the receptacle within the grenade-shell is shown in Figs. 6 and `7. :Here asuitable stopper, z', 'closes the open end of the receptacle C. An elastic 'packing consisting of a collar or sleeve, k, having a flange, k', is employed 15 to give an elastic connection between theshell and receptacle, and to confine thelatter-within the shell.
